Anyone tried a Digilux 600W Metal Halide?

Hey everyone,
I'm looking to buy a 600 watt metal halide to run with my Lumatec digital ballast. I see lots of 600 watt MH conversion bulbs, but they only crank out about 50,000 lumens. Then I saw the Digilux 600W Metal Halide which claims to push 75,000 lumens (NOT a conversion bulb). This seems like just what I'm looking for, but before I hand over my cash, I thought I'd see if anyone's tried one.

I'd appreciate any info about this bulb, or any you would recommend in its place. Thanks in advance!!!

can't vouch for the mh, but i run digilux 600W HPS on a lumatek ballast for a month and half now, No problems Whatsoever and got the bulb on sale for 55$

Yea they run great! i have one rocking in my veg room right now for about a month no problems( they are pricey though)But i went with it because of the lumen output

Hmm... I just called around to my local shops, and 2 out of 3 said they discontinued Digilux because they were getting too many returns... I'm still torn... That extra 25,000 lumens sure sounds nice. Found that bulb here for $59... Might just give it a shot...
